PAINT COMPOSITION AND PROCESS OF MAKING THE SAME.

No Drawing.

To all whom it may concern lie it known that I, Anontnnnn S. l). Till- 'ri.n, a subject of the King of Great Britain, residing at Nashville, in the county of .l.)a vidson and State. of 'lennessee, have invented a new and useful Paint Composition and Process of Making the Same, of which the :tollowing is a specification.

The paint forming the subject-matter ot' the present invention has special application in connection with the shell of gasholders or gasometers. This shell dips as is well known into a body of water more or less saturated with light oils such as hydrocarbon oils, benzol, and the like deposited thereon by condensation from the carbureted wateugas.

The object of my invention is to produce a paint which when spread over the surface of the gasoinetcr shell, will resist the action of these oils, the coat of paint being thus lct't unimpaired and protecting the metal of which the shell is constructed.

The process 01' method of compounding the ingredients of the paint may be described as follows :-To prepare the vehicle of my compound I dissolve for example titty (50) pounds of resin in its own weight oi petroleun'l spirit such as gasolene, benzin or equivalent hydrocarl'ion). I then heat 50 pounds of linseed oil (raw or boiled) with live pounds of red lead and five (5) pounds of litharge to a consistence such as to solidify on cooling. This mixture (of linseed oil, red lead, and litharge) while hot is dissolved in fifty (50) pounds of turpentine. This solution is then mixed with the solution of rosin in the petroleum spirit referred to and serves as the vehicle. To make a durable paint, a proper proportion (to suit the painter) of Venetian red (red oxid, or equivalent mineral or carbon pigments or any combination of the same) is added; and it it be desired that the paint shall dry quickly it may be thinned with gasolene. and just before applying, adding a little red lead thinned down with sufficient boiled linseed oil to cause the mixture to pass through a 120 mesh sieve before running it into the bulk. stirring the latter during admixture. To the mass (with or without the final admixture of strained red lead aforesaid) is added about four (4) per cent. by weight: of zinc ehromate, when the compound is ready for use.

If the ingredients are mixed in smaller Specification of Letters Patent.

quantities, the same relative proptn'tions by weight as outlined above should be adhered to. the specific weights given serving merely as an example. To maintain the proper relative [n'oportions and at the same time vary the weights ot the ingredients. would obviously lall within the purview of the practical painter.

llaving described my invention, what I claim is 1. in the maiuilaeture oi paint, the process ol dissolving a quantity of. resin in a hy- (ll'Ut'tHlKlIl, then heating a quantity of linseed oil mixed with red lead and litharge to a consistent-e such that the mass solidifies on cooling, dissolving said mass while hot in a suitable quantity of turpentine, and adding the solution to the original solution of resin and hydrocarbon.

9. ln the mauli't'acturo of paint, the process oi. dissolving a suitable quantity of rosin in its own weight oi. 'ietroloum spirit, heating a mixture ol linseed oil with a quantity of red laid and litharge to a point where the mass solidifies on cooling, dissolving said mass while hot in turpentine, and adding the solution to the original solution of rosin and petroleum spirit.

3. In the manufacture of paint, the process o't dissolving titty pounds of rosin in its own weight of benzin, heating titty pounds of linseed oil with live pounds 01 red lead and five pounds o'l. litharge to a point where the mass solidifies on cooling, dissolving said mass while hot in fiitty pounds ol turpentine. and adding thereto the original solution o't rosin in benzin.

4. ln a paint composition the combina tion of a vehicle conn'msed of a solution oi titty pounds of rosin in fifty pounds of benzin, mixed with a solution oi? fi'lty pounds of linseed oil solidified with five pounds of red lead and five pounds oi. lithargo, in titty pounds of turpentine. a pigment mixed therewith. and a metallic chron'iate forming about four per cent. ol the entire mixture.

5. To a paint con'iposition the combination ot a vehicle composed of a solution of fifty pounds of rosin in fifty pounds of benzin. mixed with a solution of fifty pounds of linseed oil solidified with five pounds ot red lead and live pounds o'l. litharge, in fifty pounds of turpentine. an insoluble pigment mixed therewith, and tour per cent. by weight of the entire mass. of zinc chromate.

(3. In a paint composition the combination of a vehicle composed of a solution of fifty pounds of rosin in fifty pounds of benzin, mixed with a solution of fifty pounds of linseed oil solidified with five pounds of red lead and five pounds of litharge, in fifty pounds of turpentine, a mineral pigment mixed therewith, a gasolene thinner, and four per cent. by weight of the mass, of zinc ehromate.

7. In a paint composition the combination of a vehicle composed of a solution of fifty pounds of rosin in fifty pounds of benzin, mixed with a solution of fifty pounds of linseed oil solidified with five pounds of red sieve, and substantially four per cent. of zinc chromate.

In testimony whereof I afiiX my signature, 1n presence of two witnesses.
